Written summary
AEET Energy Group GmbH is a German company headquartered in Bad Gandersheim, Germany, that operates primarily as a photovoltaic wholesale partner and installation-support network rather than as a panel manufacturer in the traditional sense. It distributes solar modules across a network of more than 500 certified specialist partners in Germany and broader European markets. ET Solar, formally trading as Jiankai Sunshine New Energy Technology and founded in 2005, is a dedicated Chinese panel manufacturer headquartered in Nanjing, China. ET Solar became state-owned in 2018 and has historically held a position on BloombergNEF Tier 1 bankability lists, with an estimated annual production capacity in the range of 1.7 GW. In terms of institutional manufacturing footprint and bankability credentials, ET Solar holds the stronger position as an original equipment manufacturer.
AEET's wholesale model means buyers get access to a broad multi-brand module portfolio spanning residential, commercial, and small-utility applications, with the practical advantage of European warehouse stock and short delivery times - a meaningful differentiator for European installers managing project timelines. ET Solar manufactures its own monocrystalline PERC and bifacial modules, with product lines designed for commercial rooftop and utility-scale ground-mount use cases. ET Solar panels carry a 10-year standard product warranty and a 25-year performance guarantee, terms that are fairly standard in the mid-tier Chinese segment, though customer feedback has flagged some friction when pursuing warranty claims through overseas support channels.
For a buyer specifically seeking a bankable, single-origin panel manufacturer with a defined production lineage, ET Solar is the more conventional choice - particularly for larger utility or commercial projects where lender bankability is required. AEET serves a different function: European installers and distributors who prioritize consolidated local supply and flexible multi-brand sourcing will find it more relevant. The two are not directly interchangeable, as AEET is a distribution platform and ET Solar is a manufacturer.
